Pilot Valve Schematic Needed

[Bob R]

Hey all, I have a bad pilot valve on my 69 M20E. It appears someone took this apart and put the diaphragm in backwards and even left two screws out. Regardless, the diaphragm is pretty tore up and I am sure I can find the rubber to make another. However, I want to make sure about gaskets and such so I was looking for a schematic. Anyone happen to have one and/or know where I might purchase the diaphragm?

Thanks, Bob

Bob,

See if you can remind me again... which one is the pilot valve?

Is that connected to the L/R knob for the Brittain?

or the on/off button?

or something completely different? 

Fuzzy memory challenge...
